DUKE A. WILKINSON AND BEN A. AUSTIN, OF SHAMROCK, TEXAS.

HOG-THOUGH.

f0 all whom it may concern Be it known that we, DUKE A. Vrmunson and BENA. AUSTIN, citizens of the United States, residing at Shamrock, in thecounty of Wheeler, State of Texas, have invented a new and usefulHog-Trough, of which the following is a specification.

This invention relates to feeding troughs for pig-sties.

The objects of the invention are, in a novel and practical manner, so toconstruct the feeding trough as to permit of its being shifted from theinterior to the exterior of the sty to receive a supply of food, and asreadily to be returned to its feeding or dispensing position; tofacilitate the removal of the trough for purposes of cleansing orrepair; to preclude the possiblity of any overturning of the trough eventhough a number of swine should crowd therein in an effort to secure thefood; and finally, to improve the construction and increase theefiiciency of structures of this character.

WVith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelarrangement and combination of parts of a feeding trough for pig sties,as will be hereinafter fully described and claimed.

In the accompanying drawings:Figure 1 is a view in vertical longitudinalsection through a portion of a sty, showing the same equipped with theimprovements of the present invention. Fig. 2 is a top plan View. Fig. 3is a view in front elevation.

The sty, designated generally 1, may be of any preferred construction,and is provided at one end with two guards 2 that project from thesides, are spaced any desired distance from the bottom 3 of the sty, andare secured in part to two extensions 4 constituting continuations ofthe sides, the guards, to meet the requirements presently to bedescribed, being extended outward and inward beyond the front wall 5 ofthe sty.

Arranged to be moved through the opening formed by the space between theguards and the bottom of the sty is an ordinary V-shaped trough 6, theend walls 7 of which are of rectangular contour and are disposed betweenthe bottom and the guards, the two latter parts constituting guides tocause the trough to move easily to and from food supplying position, andalso to be held against tilting or overturning should one Specificationof Letters Patent.

or more swine, in a manner characteristic of such animals, climb intothe trough in a voracious attempt to secure the food.

Carried by or formed integral with the upper portion of each of thetrough walls 7 is a rack bar 8, and these bars engage mutilated gears 9disposed at the end portions of a roller 10 formed with terminaljournals 11 that work in hearings in the extensions at. The teeth of thegears, which are disposed around about one-half of the circumference ofthe roller, may be integral with the latter, or may be made from lengthsof wood or metal, and secured in any suitable manner thereto. From astandpoint of economy, it will generally be preferred to construct theroller, gears and rack bars of wood, thus to enable any carpenter ofordinary ability to build the sty.

The means for rotating the roller, to cause the gears to reciprocate thetrough, consists of a lever 12 the free 'end of which is designed tocontact with the front wall of the sty, when the trough is in feedingposition, thus to render it impossible for the swine to unmesh the rackbars from the gears and drag the trough into the sty, which incidentwould leave an opening through which the animals could escape. \Vhen thetrough is shifted to charging position, the lever will lie in asubstantially horizontal plane, and thus maintain the rack bars inmeshed relations with the gears. If, however, it be desired to removethe trough from the sty for any purpose,

the last described movement of the roller will be continued until themutilated portions of the gears or roller are brought beneath the rackbars, whereupon the trough may, by hand, be pushed inward a sufficientdistance to clear the rack bar of the guards and thus permit readyremoval of the trough.

In constructing the racks and levers, there will be allowed suilicientplay between the coacting parts to preclude any binding from moisture sothat the trough may at all times, be reciprocated freely irrespective ofthe condition of the weather.

The ii'nprovements herein defined are simple in character, but will befound to coact in a manner to insure effective operation at all times.

lVhat is claimed is 1. A sty, horizontally disposed guards spaced fromand arranged parallel with the floor of the sty, a trough having endsdisposed beneath the guards, 'aok bars carried by the ends, a toothedroller ooacting with the rack bars and adapted to positively drive saidtrough, a portion of the toothed roller removed to thereby allow saidtrough to be removed from and installed in position in the sty.

2. The combination of an inclosure having an opening provided with waysextending into and out of the same, a sliding trough mounted in theways, rack bars carried by said trough, a toothed roller coacting withthe rack bars adapted to positively drive said trough, and adapted toretain said trough parallel to the end of said inclosure, a portion ofthe toothed roller removed to thereby allow said trough to be readilyremoved and installed in position within said ways. 3. The combinationof an inclosure having an opening and provided with ways eX- tendinginto and out of the same, a sliding trough mounted in the ways, rackbars carried by the ends of said trough, a toothed roller coacting withthe rack bars and adapted to move said trough in and out of saidinclosure in a parallel manner, said toothed roller having mutilatedgears to thereby allow said trough to be readily removed and inserted inposition in said ways, a lever carried by the roller and adapted torotate the latter to limit the inward movement of the trough relative tothe inclosure.

In testimony that we claim the foregoing as our own, we have heretoafiiXed our signatures in the presence of two witnesses.
